A. Schedule A - Equipment to be Installed by ESCO

A.1. Lighting Retrofit

The following sections describe the interior and exterior lighting scope of work proposed to the City for implementation. The sections are partitioned on retrofit type and facilities covered within that retrofit type.

REPLACE T-12 LIGHTING WITH T-8 TECHNOLOGY

Fluorescent lighting has been used for decades. T-12 fluorescent lamps with magnetic ballasts were once the standard of energy efficient lighting when compared to incandescent lighting. Through the years, improvements in technology have enabled greater energy efficiency in fluorescent lighting. These improvements allow for lower operating and maintenance expenses as well as better light output for building occupants.

The new standard of energy efficient lighting is T-8 fluorescent lamps. These lamps coupled with electronic ballasts draw approximately two-thirds of the power of comparable T-12 lamps with magnetic ballasts. Significant power consumption occurs in the ballast of T-12 lighting technology. The magnetic ballast acts as a transformer for incoming voltage, increasing the voltage and current to illuminate the lamp. T-8 lighting technology utilizes electronic ballasts with solid state devices to increase voltage; solid state transformers draw significantly less power when compared to standard wire coil type transformers.

In addition to increased energy efficiency, T-8 lamps with electronic ballasts offer significant improvements with regards to visibility and comfort. Many individuals complain of discomfort caused by fluorescent lighting. The cause of this discomfort is often due to T-12 lighting with magnetic ballasts. T-12 lighting technology is dependent on the frequency of incoming power; the standard power frequency in the United States is 60 Hertz (Hz). T-12 magnetic ballasts convert the incoming voltage from 60 Hz to 120 Hz. Therefore, light output and refresh rate on the lamp is occurring at 120 Hz – the human body can interpret refresh rates of up to 400 Hz. Thus, individuals who can sense the flicker of the T-12 lamp can feel discomfort. T-8 ballast technology converts the incoming 60 Hz voltage to 40 to 44 kilohertz (kHz). The T-8 lamp output and refresh frequency is significantly higher than what a human body can interpret; effectively eliminating any discomfort due to fluorescent lighting.

With the higher output frequency of the electronic ballast, T-8 lamps have a higher average lamp life than T-12 lamps. T-8 lighting also has a higher color rendering index (CRI) and color temperature when compared to comparable T-12 lighting.

The above retrofit is proposed at the following facilities:

• Cultural Center



• Hepburn Center

• DPW Administration

• DPW Garage

• DPW Warehouse

RETROFIT OLDER T-8 LIGHTING WITH NEW GENERATION T8 LIGHTING

As indicated above, T8 fluorescent lighting is the new standard for energy efficient lighting. This retrofit proposes replacing older generation, 32 watt T8 lamps with the newer 25 watt or 28 watt T-8 technology. The lower light levels requirements in many spaces make the installation of lower watt lamps an ideal application.


• Municipal Complex Police Department

• Municipal Complex: Commissioner Chamber

• Municipal Complex: City Hall

• Cultural Center

• Hepburn Center

• Crew Quarters

• Warehouse

• Fire Station 60

REPLACE HID LIGHTING WITH T-8 TECHNOLOGY

High intensity discharge (HID) lamps are frequently used in storage spaces where lights are left on/off for longer periods (to avoid cycling lights on/off). Although the light output from HID lamps is clear and sharp, they have a high power draw, typically from 400-1100 Watts per fixture, and a long re-strike time. Re-strike time is the time required before the HID lamp can be re-lit, and ranges from 15-20 minutes. HID lamps have an average lamp life of 10,000 hours.

High bay T-8 fluorescent lamps provide clear and sharp lighting at a fraction of the power draw; average lamp life is 15,000 hours and they do not suffer from the long re-strike time.


• DPW Warehouse

• Fire Station 60



REPLACE INCANDESCENT LIGHTING WITH COMPACT FLUORESCENT TECHNOLOGY

Incandescent light lamps are very energy inefficient; they create light by heating a thin wire filament which glows and gives off light. Interestingly, approximately 5% of the energy input creates the light while the remaining 95% of the energy input is converted to heat dissipated into the surrounding area. The filament has a life cycle of about 1,000 hours before it fails due to the heat.

A fluorescent lamp is much more energy efficient when compared to an incandescent lamp. Instead of using heat to provide light, the energy is used to excite vapor gas housed inside the bulb which then produces visible light. Because more energy goes into producing light rather than heat, fluorescent lamps are approximately 75% more efficient than incandescent bulbs of similar intensity. In addition to reducing energy consumption, fluorescent lamps have a life cycle 8 to 10 times that of incandescent lamps, or about 8,000 to 10,000 hours. A reduction in heat output can also be felt in the surroundings.


• Cultural Center

• Hepburn Center


REPLACE COMPACT FLUORESCENT OR INCANDESCENT LIGHTING WITH LED TECHNOLOGY

LED technology brings a host of benefits not realized in CFL and Incandescent lights. These benefits include longer life, greater energy efficiency, ecologically friendly, durability, light focus, instant on, and so on. This proposed retrofit takes advantage of lower wattage LED technology capable of replacing existing incandescent and compact fluorescent fixtures.


• Golden Isles Guard House


REPLACE HID LIGHTING WITH LED TECHNOLOGY

This proposed retrofit takes advantage of LED technology capable by replacing HID fixtures in a variety of spaces and usage settings.


• Municipal Complex Police Department


• Cultural Center



• Hepburn Center

• Fire Station 60

INSTALL OCCUPANCY SENSORS

Occupancy sensors are recommended for “group” areas or work spaces where photocells are not feasible, such as meeting rooms, cafeterias, multipurpose rooms, classrooms and designated offices. In areas such as storage spaces that have gone from HID fixtures to fluorescent, occupancy sensors will be installed that can be adjusted to provide a shut off delay of up to twenty minutes to eliminate rapid or excessive cycling of lamps.

The use of photocells is recommended in areas where existing ambient light levels provide an opportunity for additional savings.

Occupancy based controls will be installed in vending machines with non-perishable snacks and beverages to reduce electrical consumption during low occupancy periods.

The above scope is proposed at the following facilities:

• Municipal Complex

• Cultural Center

• Hepburn Center

• DPW Administration and Garage

• Warehouse

• Fire Station 60

SAVINGS FROM LIGHTING IMPROVEMENTS

A detailed room by room survey of lighting fixtures, types, wattage, etc. was performed during the audit to accurately assess the existing lighting type and quantity; the results are contained in the Appendix. Also in the Appendix are the results of the data logging sessions, sorted by space type (common areas, computer rooms, hallways, conference rooms, etc.), and the space operating hours.

The energy and cost savings were developed using the Carrier HAP energy simulation software package (energy modeling) and verified through spreadsheet analysis. The inputs used in the post-implementation model included the higher efficiency lighting fixtures (lower wattage), runtime reductions to match the data logging data for actual occupancy, occupancy sensors, etc.

The table below illustrates a sample of the results obtained from the measured data.



HEPBURN CENTER: LIGHTING VS. OCCUPANCY DATA

The electrical load reductions as a result of the lighting retrofits also reduces the heat load from the existing lighting fixtures. This reduction in heat provides additional savings due to the reduced required capacity of the HVAC equipment. The cooling benefit is accounted for in the savings for of this facility improvement measure and is calculated with the function of the energy model. Detailed savings calculations are available in the Appendix.

The following table represents the calculated energy savings:

MEASUREMENT AND VERIFICATION – LIGHTING

The Measurement and Verification (M&V) for the Lighting Retrofit and Occupancy Sensor Facility Improvement Measure (FIM) will be International Performance Measurement and Verification Protocol (IPMVP) Option A: Retrofit Isolation: Key



Parameter Measurement. A Detailed M&V Plan is available in the contract document, Exhibit C.

A.2. Electric Rate Change at the Cultural Center The Municipal Complex is currently on a Florida Power and Light (FP&L) Commercial/Industrial Load Control Program (CILC-1(G)) electric rate structure. This rate structure provides lower consumption and demand charges to coincide with peak/seasonal demand. In return for the lower rates, FPL reserves the right to reduce or suspend electric service for a pre-determined period of time, and with advance warning.

To avoid complete electric shutdown, the facility must be equipped with a generator capable of providing 100% back up power.

1000 kW Backup Generator

The generator installed for the Municipal Complex is large enough to provide backup power for both the Municipal Complex and the Cultural Center. Both buildings are connected to an automatic transfer switch that activates the generator and bypass the electrical source feed for the building to the generator, should power interruption every occur.

Unlike the Municipal Complex, the Cultural Center is on a General Service Demand (GSD-1) rate, which has higher consumption and demand rates than the CILC rates. Although the Cultural Center has 100% backup generation, it does not qualify for the CILC rates because annual peak demand usage of the Cultural Center is roughly 100 kW while the CILC rate structure requires a minimum of 200 kW.

ELECTRIC RATE CHANGE PROJECT SCOPE

This FIM combines the electric feeds to the Municipal Complex and the Cultural Center into one electric meter so the Cultural Center can be billed at the lower CILC rate. An electric submeter will be installed for each building to allow the Finance Department to monitor and internally bill the corresponding departments. The submeter will communicate with the existing Building Automation System (BAS) to provide monthly



electric consumption values. This data will be used by the City to accurately divide the FPL electric bill between the Municipal Complex and the Cultural Center.

SAVINGS FROM RATE CHANGE

The energy and cost savings were developed using an energy model and verified with spreadsheet analysis. Both the Municipal Complex and Cultural Center energy models were calibrated to closely match the baseline billing data, and the Cultural Center annual usage profile was adjusted to match the CILC rate structure. The difference between the original profile and the adjusted profile determined the dollar savings associated with this FIM. Since this FIM is strictly a rate change, there are no electrical consumption or demand units saved. Energy model results are provided in the Appendix of this report.

The resulting dollar savings is for this FIM $2,074.

MEASUREMENT AND VERIFICATION – RATE CHANGE

The Measurement and Verification (M&V) of the Electric Rate Change FIM will be International Performance Measurement and Verification Protocol (IPMVP) Option A: Retrofit Isolation: Key Parameter Measurement. A Detailed M&V Plan is available in the contract document, Exhibit C.

A.3. Chiller Replacement at Municipal Complex Chillers are the single largest energy consumers in commercial buildings with peaks in electrical power usage during hot summer afternoons. Most chiller plants are oversized for capacity, but even properly sized chillers operate most of the time at low, part-load efficiencies.

As detailed in the Existing Conditions section of this report, the Municipal Complex utilizes two (2) Trane air-cooled chillers, each with two compressors – one chiller at approximately 90 tons and the other at approximately 80 tons of capacity. Chiller #1 operates 24 hours a day and varies in the number of compressors used, and Chiller #2 comes on as needed when the building load is high enough to require additional cooling capacity. Data logging has revealed that Chiller #2 seldom runs.

Both chillers are original to the building, and were installed in 1994. The chillers are at the end of their useful life and are showing signs of wear from weather and outdoor conditions. Chiller #1 was observed operating at 120% current limit, had two (2) condenser fans that were not operational, water leaks, and deteriorating insulation.



Air-Cooled Chiller Conditions

A.1.A. CHILLER REPLACEMENT SCOPE

This FIM recommends replacing Chiller #1 with a 130 ton, high efficiency air-cooled chiller with variable speed screw compressors. We recommend keeping Chiller #2 in place to achieve redundancy for the chiller plant. The higher efficiency chiller will be installed in the same location as the existing machine, and the pumps, piping and electrical service will not require alterations. The new chiller will be connected to the building automation system and will be controlled to maximize the part load efficiencies associated with this new machine.

SAVINGS

The energy and cost savings were developed using an energy model. Savings are realized from increased operating efficiencies and maximizing the control capabilities of the building automation system and the chiller’s part load efficiencies. The following table represents the calculated energy savings:

MEASUREMENT AND VERIFICATION

The Measurement and Verification (M&V) of the Municipal Complex Chiller Replacement FIM will be International Performance Measurement and Verification Protocol (IPMVP) Type A: Retrofit Isolation: Key Parameter Measurement. The key parameter to be measured is kW/ton. The Building Automation System is capable of collecting the data necessary to determine kW/ton efficiency values of the new machine. The existing chiller’s kW/ton value will be accepted as part of the energy model calibration. A Detailed M&V Plan is available in the contract document, Exhibit C.



A.4. VAV Box Replacement and Improved Return Air Flow at Municipal Complex

The Commissions Chambers at the Municipal Complex is cooled by the same chilled-water RTU that cools the Police Department, a 24 hour a day operation. While cooling for the Police Department is a 24 hour operation, the Commission Chamber is used an estimated 20 hours a month.

As reported earlier, many components of the air distribution system have fallen in disrepair, including the two (2) VAV boxes responsible to regulating temperature in the Chamber. This has resulted in the 24-hour cooling of this space as well as frequent reports of discomfort by occupants that are too cold.

It is important to note that we suspect that many of the VAV boxes at the Municipal Complex may also be inoperative, but the scope of this project did not support investigating improvements with little to no savings component.

While investigating this issue the City informed Siemens that the Chambers also lacked return air ductwork. The second floor above the Chambers and Police Department is an open plenum for return air to travel back to the RTU for mixing and re-conditioning. The Chambers is separated from the Police Department, on the first floor, by an exterior breeze way. Although the original construction plans called for return air ductwork to connect the two spaces, this ductwork was never installed (see picture below on left). Return air is, however, able to leave the Chambers through two large fire dampers located above the Chamber’s ceiling. This allows return air to use the free plenum above the ceiling tiles as a path back to the RTU (see picture below on right).

With assistance and guidance of City staff, and upon further investigation, we found that Chamber’s return air has a path to leave the space, but does not have a path back to the RTU – return air flow is blocked by hallway fire walls and east half of the Police Department’s second floor. The illustration below shows the fire walls in red and restricted flow of the return air in the building.



VAV AND AIR FLOW FIM SCOPE

The scope includes replacing or repairing the two inoperable VAV boxes for the Chambers. New or refurbished VAVs will allow the system to modulate the amount of conditioned air that enters the space, the temperature of supply air, and the cooling times. The new VAVs will be reconnected to, and controlled from, the building automation system. City staff will be responsible to schedule the VAV usage as needed based on scheduled meetings and duration. The intentions are to command the VAV dampers to open one hour before a scheduled meeting in order to pre-cool the space and to return to a minimum damper position one hour after the meeting has concluded.

In addition to the new VAV boxes, the fire walls restricting the flow of return air back to the RTU will be equipped with fire dampers. Fire dampers are approved openings in fire walls that are designed to close with high temperatures/heat. Dampers will remain open otherwise.

The Measurement and Verification (M&V) of this FIM will be International Performance Measurement and Verification Protocol (IPMVP) Option E: Stipulated. A Detailed M&V Plan is available in the contract document, Exhibit C.

A.5. Chilled-Water RTU Replacement at Municipal Complex The Ebtron flow stations in the chilled-water RTU serving the Police Department and Commissioners Chambers has not been operational for several years. Flow stations modulate the flow of outside air into the unit by varying the positions of the outdoor air damper. Outdoor air is brought into building to achieve the proper number of air turnovers to achieve desired indoor air quality levels. The number of air turnovers can depend on building occupancy, cooling load requirements, or time of day. With the replacement of the outdoor air flow stations, outside air flow can be properly monitored and controlled. By properly scheduling the amount of outside air conditioned, based on demand, less unconditioned air needs to be cooled. The reduced cooling requirements imposed on the unit produces energy savings.

Existing Ebtron Flow Station

In addition to failed flow stations, the RTU itself has reached the end of its useful life. Many panels on the unit have rusted out allowing significant amounts of infiltration. The failed control valve has resulted in water leaks and biological growth on its exterior. Door panels on the supply air side leak significant amounts of conditioned



air, which reduces the amount of conditioned air put into spaces. This forces the RTU to work more than necessary.

Due to the units deteriorated condition, the unit is prohibited from operating beyond 50 Hz due to its tendency to vibrate and shake the steel stand it sits upon. The steel stands also show signed of deterioration and rust.

Deteriorating Chilled-Water RTU

PROJECT SCOPE

This FIM will replace the chilled-water RTU and the Ebtron flow station at the Municipal Complex. The energy models indicated that the current use of variable frequency drives effectively limits the intake of outdoor air during unoccupied periods. The RTU is currently controlled based on temperature feedback from the VAV thermostats. As occupancy increases, thermal and ventilation load increase. The VFDs react accordingly and, in effect, accomplish the same goal intended by the replacement of the Ebtron flow station. This FIM, therefore, addresses the replacement of the RTU, as it was originally installed, based on structural and equipment need.

SAVINGS

The energy and cost savings were developed using an energy model. Savings are realized from resuming control of operational flow stations to allow the proper amount of outdoor air into each air handling unit based on time of day needs.

A.6. Cultural Center RTU Replacements Packaged DX roof top units’ (RTUs) lifetimes vary depending on the types of fans and coils, and on maintenance practices. Typically, RTU motors, dampers, and coils last between 10 and 15 years before requiring replacement. The same applies to split direct expansion (DX) systems, rooftops units, and air-cooled condensers. Water damage due to condensation and rain infiltration is common in such equipment and also reduces the expected lifetimes.

Replacement of HVAC equipment is a high cost improvement measure that typically is vital when the current units have reached the end of their useful lifetime. Financial paybacks are traditionally longer for this improvement measure but should not be judged solely on their economic feasibility due to their critical function in the overall building’s HVAC system.

PROJECT SCOPE

Most of the RTUs at the Cultural Center are 1997 vintage. These have been identified for replacement based on age, efficiency and condition. The remaining units are either new or have not reached the end of their useful life; replacing these units is not economically beneficial.

The following are the 1997 RTUs that have been identified for replacement:

• Unit Serving Kitchen

• Unit Serving Administration Offices,

• Three (3) Units Serving Auditorium

• Unit Serving West Wing Rooms,

• Unit Serving Restrooms and Hallways

Each of the above mentioned units are Carrier models of approximately 11 SEER efficiencies. These will be replaced with 15 SEER Carrier models of the same size to ensure proper alignment with the existing footprints.

SAVINGS

The energy and cost savings were developed using an energy model and verified with spreadsheet analysis. Savings are realized from the improved, higher efficiency of the new RTUs.

A.7. Plug Load Management Miscellaneous plug loads such as copiers, computers, computer screens, coffee machines, and water fountains can make up a substantial portion of a building’s energy consumption. And while some of these loads may operate efficiently in standby during unoccupied periods, many plug load devices leak significant energy in standby or off mode. BERT, which stands for Best Energy Reduction Technologies, is a patented Wi-Fi based solution that automatically and remotely controls and schedules plug load devices to turn on/off during unoccupied hours.

BERT controllers function with a built in relay that severs the electrical connection between the device and the electrical receptacle. Should use of the device become necessary, each BERT controller is equipped with an override button to release the connected device from its OFF command. The BERT units will not turn off again until the next scheduled shut-off time.

In order to identify plug-load devices suitable for Bert, data logging sessions where conducted on a variety of plug-load devices at the following facilities (facilities with the largest plug loads): Municipal Complex, Hepburn Center, and DPW Administration Building. Following list are devices that are generally good candidates for Bert, and that were logged during the audit.

• Water Fountains

• Workstations with Monitors

• Laptop with Docking stations

• Printers

• Vending Machines

• Letter Sorter

• Coffee Maker

The results of the data logging are provided in the Appendix of this report.

PROJECT SCOPE



This facility improvement measure (FIM) is the installation of wireless Bert controllers and integration into the existing Wi-Fi Network; scheduling for BERT will be managed from a central computer.

The data collection process identified many devices that do not warrant BERT; many City employees shut off equipment at the end of the work day. Energy leaks through electric receptacles are not significant enough to produce energy savings of value.

However, several devices would benefit from BERT equipment such as:

• Municipal Complex – Printers (large and small)

• Hepburn Center – Printers and drinking fountains

• DPW Administration Building – Printers and Coffee Maker

The quantities and locations of the BERT equipment is provided within the Appendix, along with calculated energy savings. The schedules associated with the equipment are as follows:

• Municipal Complex – OFF from 6PM to 7AM (Monday through Friday ) and OFF Saturday and Sundays

• Hepburn Center – OFF from 9PM to 7AM (Monday through Friday ) and OFF Saturday and Sundays

• DPW Administration Building – OFF from 6PM to 6AM (Monday through Friday ) and OFF Saturday and Sundays

SAVINGS

The energy and cost savings were developed using the Carrier HAP energy model and verified with spreadsheet analysis. Savings are generated by eliminating the power draws of each plug-load device during scheduled off times.

A.9. Upgrade Trane Tracer Software at Municipal Complex The Municipal Complex HVAC equipment is controlled using a building automation system (BAS), a Trane Tracer 100, installed during construction in 1994. The system is operating as intended although the graphical user interface is very outdated; the City has requested that Siemens upgrade the system.

PROJECT SCOPE

The Tracer 100 will be replaced while allowing existing unit controllers to remain in place. Unit controllers will remain on the old communication bus but can be replaced new BACnet controllers upon controller failure.

The upgrade to the control system will provide a BACnet system which will be a web based graphical user interface. The City will need to provide an internet access connection for remote connectivity. This scope provides for a dedicated Ethernet network (City to provide Static IP) for the System Controllers (SC’s) including installation.

The new system will include the following only:

• Enterprise Server

• Web Enabled Building Controller

• Legacy Protocol to BACnet



• Installation of new bridge controller to communicate between legacy controllers and BACnet building controller

• Installation of new building controller

• Programming and Startup of the new control system

• Set up of trend logs for each piece of equipment

• 3D Graphics to include ( Exterior Home page, Chiller System, HVAC Equipment, Up to 2 Floor Plans)

• Training (8 hours)

A.12. Water Conservation This FIM addresses the reduction of water consumption, wastewater production, and hot water energy use through the installation of high efficient plumbing products and controls. The water efficiency devices are detailed below and were selected for their efficiency, durability, minimal maintenance requirement, and improved hygiene.

All of the retrofits meet or exceed the Energy Act of 1992, which mandates the use toilets with 1.6 gallons per flush, showerheads that consume no more than 2.5 gallons per minute, and faucets that deliver less than or equal to 2.0 gallons per minute.

PROJECT SCOPE

Staff and Public Restroom Faucets: Installation of 0.5 gallon per minute (GPM) flow restrictors on faucets currently equipped with 2.0 to 3.0 GPM flow restrictors. The flow restrictors will be tamper proof requiring special keys for removal for any necessary maintenance; maintenance keys will be supplied to the maintenance group. Additionally, current faucets will be repaired and/or replaced as necessary to eliminate leaks. This scope is applicable at the following facilities:

• Hepburn Center




• Garage

• Crew Quarters

• Golden Isles Guard House

General Purpose Sinks: Installation of 1.5 GPM flow restrictors on faucets currently equipped with 2.0 to 3.0 GPM flow restrictors. The flow restrictors will be tamper proof requiring special keys for removal for any necessary maintenance; maintenance keys will be supplied to the maintenance group. Additionally, current faucets will be repaired and/or replaced as necessary to eliminate leaks. This scope is applicable at the following facilities:

• Crew Quarters

• Golden Isles Tennis Center

• Fire Station #60


Single Spigot Cold Only Faucets: Replace single spigot, cold only faucets with delay close (push button) faucet. The push button faucets are designed to deliver ample water for washing hands while eliminating the possibility of leaving the faucet running. This scope is applicable at the following facilities:


Water Closet: Replacing 3.5 to 5.0 GPF water closets with 1.28 gallons per flush (GPF) water closet and flush valve. The new fixtures with Sloan flush valves are engineered to ensure they provide flushing performance that meets or exceeds ASME and ANSI performance standards for low-consumption toilets. These toilets are designed with large fully glazed trapways and a state-of-the-art siphon jet system to break up and keep the waste moving without blockage. This scope is applicable at the following facilities:


Tank Toilet: Installation of 1.0 gallons per flush (GPF) pressurized tank toilets in place of existing equipment that currently consumes 3.5 GPF. This scope is applicable at the following facilities:


Urinal: Installation of 0.5 or 1.0 GPF flush valve (dependent on urinal type). Urinals requiring this retrofit are currently consuming 1.5 GPF or more; the new flush valves will cut the current consumption in half and still provide ample water for flushing the fixture. This scope is applicable at the following facilities:




Showers: Installation of high performance, low flow showerheads. The existing 2.5 to 5.0 GPM showerheads will be replaced with 1.5 GPM heads, and shower valves will be repaired and/or replaced as necessary to eliminate leaks. This scope is applicable at the following facilities:

• Garage

• Crew Quarters



Food Service Sinks: The food service sinks will be retrofitted with hands free foot pedal faucet controllers. These pedals will eliminate existing faucet leaks as well as help prevent the user from walking away from the sink while the water running. Most customers prefer the Pedal Valve controls since they eliminate the need to touch the faucet controls and so eliminate hand contamination at the faucets. Pedal Valve controls will be equipped with a locking mechanism for those applications where an unattended constant flow is necessary. This scope is applicable at the following facilities:

• Hepburn Center

Ice Machines: Installation of Vizion Chill heat exchanger on ice machine. This retrofit will pre-cools incoming water by recovering the energy from the purged ice water exiting the ice machine. Reducing the incoming water temperature directly lowers the cooling load of the icemaker’s refrigeration system and improves performance. This scope is applicable at the following facilities:

• Hepburn Center

• Crew Quarters


Disposition of Removed Equipment: All existing equipment will be removed and properly disposed or recycled by the contractor. Due to the probability and nature of contamination of the removed equipment, future use of the materials is not recommended and the material will not be made available for surplus.

SAVINGS

The energy and cost savings were developed using spreadsheet modeling as Carrier HAP energy models are not suitable for calculating water conservation measures outside the confines of HVAC chilled-water applications. The detailed saving analysis is provided in the Appendix.

The Measurement and Verification (M&V) of this Water Conservation FIM will be International Performance Measurement and Verification Protocol (IPMVP) Option A: Retrofit Isolation: Key Parameter Measurement. A Detailed M&V Plan is available in the contract document, Exhibit C. The hot water electric savings will use Option E: Stipulated.

A.13. Water Meters The fundamental principle behind this FIM lies in recovering some of the apparent losses in the City’s water system. Apparent losses per the American Water Works Association (AWWA) are the losses in water system operations due to meter inaccuracies, systematic data errors, and/or unauthorized consumption. This FIM will focus on recovering apparent losses in the observable decline in measurement accuracy of water meters over time and the ability to reduce operational cost associated with reading water meters. The factors affecting the decline of water meter accuracy are measurable and repeatable, which allows the resulting increase in billed meter consumption to be predicted in the future. The operational savings resulting from the installation of an AMI system are easily calculated and the numerous benefits are realized by both the City and its citizens.

The major factors influencing decline in water meter measurement accuracy are cumulative quantity of water measured through the meter over its service life and the quality of the metered water. Meter age is also a factor contributing to meter accuracy decline, but it is a secondary factor to the two factors mentioned above. Subsequently,



age is typically not considered a primary factor in determining expected meter accuracy.

The white paper entitled, “Residential Water Meter Replacement Economics“, by S. E. Davis, Sacramento, CA, 2005, is a case study of an Arizona based water district where the specific factors of cumulative water measured and meter age were evaluated in relation to one another. The conclusion of the paper was that cumulative water measured can be clearly shown as the most determining factor in estimating meter measurement accuracy. Age has historically been the parameter used as a simple benchmark used by meter manufacturers to gage meter wear, but age alone is not the most influential factor.

Accordingly, the technical basis for this FIM resides in Siemens’ practical ability to accurately discern the status of existing meter accuracies from an analysis of existing historical meter records and through meter accuracy tests performed on existing field water meters. These two parameters sufficiently benchmark existing meter conditions within a given water authority. Relying on the proven relationship between physical predictability in meter accuracy as a function of cumulative water measured, a profile or model of the efficiencies of the existing water district meter infrastructure can be constructed with confidence.

Additionally, the predictability of future meter accuracy declines within newly installed meters can be benchmarked using the same methodology described above. A process can be developed that enables Siemens to develop payback, and measurement & verification (M&V) criteria around this FIM. Because of this, Siemens can guarantee and support this FIM.

Siemens guarantees increased accuracy in water meter readings through a replacement strategy of older existing water meters. Increased meter accuracy in turn has the effect of increasing the water revenue for the City. The increased billed metered consumption is further enhanced by an associated increase in sewerage charges where the charges are based on the measured water consumption. As the water billed metered consumption increases due to more accurate measurements, the sewerage charges also increase.

The benefits for municipalities implementing this FIM are:

• Revenue enhancement to the municipal water authority;

• Operational cost savings;

• Cost avoidance of future meter failure;

• More accurate billing;

• Recovered revenue;

• Fairness (new water customers do not bear the higher proportion of costs);

• Risk reduction/persistence of revenue;

• Reduction in labor requirements;

• Financial solution to funding issues;



• Real-time data and meter reads;

• Enhanced customer service for their citizens.

Advanced Metering Infrastructure (AMI) is an innovative technology that allows water authorities to take multiple meter readings simultaneously, remotely and to various levels of automation, thereby reducing additional costs associated with reading meters. This fixed-based technology uses fixed based antennas that receive transmissions from all water meters in the service area. This data is then sent to a centralized location within the City where it can be used for billing, analysis, and resolving customer service issues. The system collects all meter readings daily and requires the least effort to perform these tasks.

In addition to the operational costs associated with meter reading, additional cost savings can also be realized through reductions in customer meter inventories. This is attributable to the standardization around the newly installed meters. The Siemens meter warranty and replacement guarantee would not necessitate high meter inventories for the staff to accommodate meter failures.

PROJECT SCOPE

Siemens recommends replacing the water meters currently found at each location with a new water meter with transponder for remote communication. With this system, the City can read the meters from a single point computer workstation without leaving a central site location. Each meter reading is stored in the reading equipment and sent to the main server when called upon. The data is then converted and synchronized with the billing software and the bill is generated. The AMI technology will have a significant and positive impact on operational costs, reading errors, worker compensation costs, risk and liabilities, thus meter reading efficiency is significantly improved.

The turnkey solution proposed by Siemens includes:

• Replacement of water meters with new units. All necessary auxiliary equipment such as curb stops, lids, nuts, boxes, bolts, and gaskets to be provided as required;

• Installation of fixed based AMI system;

• Download of billing account data from the billing system;

• Installation of meter endpoints;

• Programming of meter endpoints;

• Installation of all data collection units on existing water tower

• Installation of 60’ poles at one locations;

• Installation of system software;

• Capture and recording of GPS coordinates for each meter location;



• Upload of all critical billing account data into the billing system;

• Training & administrative support prior to project completion to ensure a functional system;

• Commissioning/verification of the system.

Table below shows the meter quantities that Siemens will install during the implementation phase of this project.

During project development, water meters were chosen among the overall population of meters within city limits; the figured below shows the locations of the test meters. The meters were removed and transported to a third party laboratory for accuracy testing.



Figure – Location of Test Meters

The selection of meters to be tested within each size group was done randomly and the laboratory tests in accordance with AWWA guidelines. Each meter was tested at three different flow rates as specified by AWWA for different meter sizes and types. The average meter accuracy was calculated as a weighted average, with weights of 15% for the low flow, 70% for the intermediate flow, and 15% for the high flow. The following tables show the results of the water meter tests.

It is important to note that water revenue calculations are based on the meter accuracy improvements of only the 1”, 1.5” and 2” meters; meters of all other sizes and designations are included in the scope of the project for which the City will benefit from any accuracy improvements that result from replacing them.

In order to estimate the water revenue increase due to improved meter accuracy the baseline annual billed meter consumption of water for each water and sewer billing tier was calculated from the data provided by the City (September 2012 through August



2013). For each billing tier, the estimated billed metered consumption with new meters is calculated as:

BMCafter = (BMCbefore) x (MAafter) / (MAbefore)

BMC [kgal] = Billed Meter Consumption

MA [%] = Meter Accuracy

And the revenue water increase for that billing tier is calculated as:

RWI= [(BMCafter) – (BMCbefore)] x (BR)

RWI [$] = Revenue Water Increase

BMC [kgal] = Billed Meter Consumption

BR [$] = Billing Rate

The table below outlines the calculated revenue increase for year 1 of the performance period.

Note: The new meter accuracy shown in the above table (98.5%) corresponds to the accuracy that Siemens is guaranteeing and is above the standard manufacturer’s guarantee.

OPERATIONS AND MAINTENANCE SAVINGS

The O&M savings derived from implementing the water meter replacement with the AMI system are based on the information supplied by the City regarding estimated reduction in operating costs related to the subcontractor required to read the meters, customer service activities, and staff re-read requirements. The total O&M savings calculated by the City for year 1 of the performance contract is $60,000.

In addition to the O&M savings, there will be savings resulting from the City-wide installation of new meters, eliminating the capital cost to replace old meters with new meters. While this is an annual cost that will be eliminated for many years, we are only including capital avoidance of $50,000 for the first five years of the project term.



AMI PROPAGATION STUDY

As part of this project development effort, a propagation study was conducted in order to design the fixed-based system of antennas that will collect meter readings and transmit them to the computer system that processes them. The propagation study is a simulation of the performance of the system and is influenced by the geographical location of the transmitters and receivers, and the topography of the area.

The AMI system was designed around two main antennas to be mounted at strategic locations across the city; these locations and antenna heights are listed in the table below.

B.1. Hallandale Beach Municipal Complex The Hallandale Beach Municipal Complex, located at 400 South Federal Hwy, is a two-story, multi-building facility housing the Police Department, Commission Chambers, and City Hall administration. The facility was built in 1994 and is approximately 53,500 square feet.

OCCUPANCY AND HOURS OF OPERATION

The building occupancy and hours of operation were obtained from various staff interviews conducted during the site visits.

The hours of operation for the City Hall section of the building are posted as Monday through Friday, 7:30AM-5:00PM. There are a reported 80 staff members working in City Hall with an unknown number of daily visitors.

The Police Department is a 24 hour operation that works in three (3) shifts. There are 147 staff members dedicated to the Police Department with 23 in-office employees working during customary business hours. Each shift has an estimated 41 police officers that frequently come and go as needed.

The Commission Chambers is reported to operate an average of 20 hours per month.

LIGHTING

The Municipal Complex underwent a lighting retrofit in 2011. During this retrofit the City installed new lighting technology and lighting control strategies, which included Lutron occupancy and daylighting sensors. During the investment grade audit occupancy sensors were observed to be operating as expected throughout the facility. The daylighting sensors reduce light levels when there is sufficient daylight available; daylight control was observed to be not functioning, likely from failed sensors.

A detailed lighting audit was conducted to determine the lamp and fixture types and quantities currently installed. The following is a brief summary of this audit indicating the lighting equipment found at this facility.

• 25 Watt incandescent fixture • Existing LED • 50 Watt incandescent fixture • 100 Watt incandescent fixture

• 13 Watt screw-in compact fluorescent fixture

• 13 Watt plug-in compact fluorescent fixture



• 2-Lamp 13 Watt plug-in compact fluorescent fixture

• 26 Watt plug-in compact fluorescent fixture


• 1-Lamp 17 Watt T8 with 2' linear fixture





• 50 Watt metal halide fixture • 100 Watt metal halide fixture • 175 Watt metal halide fixture • 400 Watt metal halide fixture • LED Exit Sign

The detailed lighting audit is provided within the Appendix on this report. In addition to this audit, a lighting occupancy sensor data logging session was conducted for a period of two (2) weeks to measure the hours of lighting at this facility. These results can also be found within the Appendix. The results of both studies (the audit and the data logging session) were utilized to calibrate the energy model for this facility.

AIR MOVING EQUIPMENT

The air distribution system throughout the Municipal Complex is variable air volume (VAV). There are approximately 57 VAV boxes which include a mix of fan powered boxes without electric reheat and, more commonly, VAV boxes with electric reheat. During the audit, various staff members reported that areas of the building become excessively cold.

Examples of VAV Boxes and Indoor Temperature Issues

Inspections of the boxes found more than 10% of the VAV boxes are not operating as intended / expected, and it is anticipated that a great many do not operate properly. However, the energy savings associated with testing each VAV box did not warrant individual testing during the IGA. The following are the identified and reported issues concerning the VAV system at this facility.

• Zone temperature does not match cooling setpoint temperature

• Supply air temperature does not match cooling setpoint temperature

• Valve positions appear inaccurate on building automation system (showing mostly closed when actually mostly open)

• Attempts to temporarily adjust VAV boxes resulted in maintenance staff manually fixing dampers to specific positions

• Some electric reheat are reported to as not operational

• Some fans in the fan powered boxes are reported as not operational

• Some VAV heating setpoints are at 45F (this is not going to call for heat)

• Some flow measurements are not registering (indicates possible problem with the VAV box)

In order to determine the total number of VAV that are no longer operational, and the individual causes of each failure, an in-depth test and troubleshooting investigation must be performed.



VAV System Inspection

BUILDING AUTOMATION SYSTEM AND EQUIPMENT OPERATION

The Municipal Complex HVAC equipment is controlled by a Trane Tracer 100 building automation system (BAS) installed during 1994 construction. The system consists of the following components:

• (4) PCM panels – each controls an AHU/RTU and one panel controls the variable secondary pump

• VAV command unit – controls approximately 57 VAV boxes

• TCM panels – each controls the primary pump based off chilled-water temperature

Each panel has a maximum of 20 available control points, with 19 control points currently being utilized with these panels. The following pictures illustrate the different controlled or trended data available of this current BAS.

E. Schedule E – Baseline Energy Consumption

Each facility investigated within the City of Hallandale Beach consists of its own dedicated electric meter, account, and corresponding billing rate structure. FPL is the primary provider of electrical service across all facilities. The following is a description of each of the different types of electric billing rate structures encountered, those facilities currently billed under each structure, and the corresponding effective rate. The effective rate is a calculated value that includes all applicable taxes and fees associated with each unit of energy. Effective rates are used in the energy calculations in order to account for all costs associated with the reduction in consumption.

General Service Non-Demand (GS-1) – This rate structure is for electric service required for commercial or industrial lighting, power and any other purpose with an electric demand of 20 kW or less. The billing structure consists of a single charge per unit of consumption (kWh).

The following table states the rates, per unit of energy, offered under this rate structure and the facilities to which they pertain.

General Service Demand (GSD-1) – This rate structure is for electric service required for commercial or industrial lighting, power and any other purpose with a measured electric demand in excess of 20 kW and less than 500 kW. Accounts with an electric demand of 20 kW or less may enter an agreement for service under this schedule based on a Demand Charge for a minimum of 21 kW. The billing structure consists of a single charge per unit of demand (kW) and a single, separate charge per unit of consumption (kWh).

Commercial/Industrial Load Control Program (CILC-1(G)) – This rate structure is for electric service provided to any commercial or industrial customer as part of the Commercial/Industrial Load Control Program Agreement. This rate structure allows FPL to control at least 200 kW of the Customer’s load or operate Backup Generation Equipment to serve at least 200 kW of the Customer’s load when FPL requires “load shedding”. The (G) designation is for a power demand of greater than 200 kW but less than 500 kW. The billing structure consists of maximum demand, load control on-peak demand, firm on-peak demand, and on-peak and off-peak kWh charges.

The on peak periods are as follows: November 1 – March 31: Monday through Friday, 6 am to 10 am and 6 pm to 10 pm, excluding Thanksgiving Day, Christmas day, and New Year’s Day; and April 1 – October 31, Monday through Friday, 12 noon to 9 pm, excluding Memorial Day, Independence Day, and Labor Day.


Sports Field Service (OS-2) – This is a transitional rate available to municipal, county and school board accounts for the operation of a football, baseball or other playground, or civic or community auditorium, when all such service is taken at the available primary distribution voltage at a single point of delivery and measured through one meter, and who were active as of October 4, 1981. Customer may also elect to receive service from other appropriate rate schedules.

Per the request of the City, 24 months (2 years) of electric data were analyzed to form a baseline for the energy savings performance contract project. Two annual periods of electric data were averaged together, by month, to form the following baseline tables and charts.

Power demand was seen at a minimum in November with a value of 221 kW, and the minimum energy consumption of 101,700 kWh occurring in February. The power demand minimum was likely the result of more temperate weather in the fall with minimal use of electric reheat. Minimum electric consumption occurs in the winter month with the reduced run hours of mechanical cooling equipment. Power demand is consistent throughout the year with the use of mechanical heating to temper discharge air and also for building heat during cooler, temperate periods of the year.

August, following the trend of other South Florida facilities exhibiting higher electric utility usage du Mechanical cooling equipment is used for the longest periods of the year during the summer months causing the highest electric usage.

Power demand was seen at a minimum in December with a value of 54 kW, and the minimum energy consumption of 4,275 kWh occurring in December. Minimum power and electric consumption occurs in the winter month period due to reduced run hours of mechanical cooling equipment. Additionally, since the Hepburn Center is a community center, occupancy may have decreased during the December holiday season.

Fire Station 60 Baseline Profile

kWh kW



The maximum power demand was seen September with a value of 48 kW, and the maximum energy consumption of 22,620 kWh occurring in March. The highest power consumption occurring in the summer months, with the maximum occurring in September, follows the trend of other facilities located in South Florida exhibiting higher electric utility usage during months with the highest outside temperatures. The highest energy consumption occurring in March may be attributed with the nature of the use of fire stations. Traditionally, residential type buildings can have different usage patterns than commercial buildings.

Power demand was seen at a minimum in July with a value of 39 kW, and the minimum energy consumption of 11,670 kWh occurring in July. The minimums occurring in July could be attributed with the recent mechanical equipment replacement that was performed at the fire house. The minimums occurring at peak temperature periods do not follow traditional South Florida historical utility trends of other facilities.

The maximum energy consumption of 733 kWh occurring in August and the minimum energy consumption occurred in January with 262 kWh. Within the 24 month utility data provided, August 2011 and September 2011 had noticeably higher energy consumption values than other months. This could be attributed by increased usage by security officers during those times. The baseline energy usage is consistent throughout the year and is not easily influenced by weather otherwise.

E.12. Existing Water Utility Consumption and Costs Each facility investigated within the City of Hallandale Beach consists of its own dedicated water meter, one for domestic water and the other for irrigation purposes (if irrigation is used at the facility). Sewer charges are associated with domestic water meter only, and the irrigation meter is strictly for water consumption. The City of Hallandale Beach supplies water to its facilities. Water is purchased from Broward County and treated by the City. The associated sewer is sent to the City of Hollywood for treatment.

The water tariff is a tiered rate and follows the prescribed table below:

Per the request of the City, 24 months (2 years) of water consumption data were analyzed to form a baseline for the energy savings performance contract project. Two annual periods of water consumption data were averaged together, by month, to form the following baseline tables and charts.

The Municipal Complex has water account number: 846910, Meter Number: 1291179, and falls under the H IC rate structure.

MUNICIPAL COMPLEX WATER CONSUMPTION

The Municipal Complex’s water usage during the provided baseline is primarily for outdoor sprinklers. Siemens was informed that this annual irrigation value is incorrect. The irrigation system was accidentally left on override during the above annual period. It has since been returned to its scheduled operation. The correction has eliminated the potential for irrigation measures. The water usage for domestic purposes is relatively consistent throughout the year, as predicted by the facility’s type and usage profile.

The Cultural Center has water account number: 851290, Meter Number: unknown, and falls under the H IC rate structure.

F. Schedule F - Savings Measurement and Calculation Formulae; Methodology to Adjust Baseline

F.1. Lighting Calculations KW Savings = Pre KW Measurement – Post KW Measurement

Annual KWH Savings = Pre Lighting Burn Hours x Pre KW Measurement – Post Lighting Burn Hours x Post KW Measurement

Annual KW Demand Savings = KW savings x demand months

Annual Dollar Savings ($) = KWH Savings x $/KWH Rate + kW demand savings x $/kW rate

F.2. Occupancy Sensors Calculations Annual Occupancy Sensor Savings (KWH) = Burn Hours Saving x Post KW

Annual Dollar Savings ($) = Occupancy Sensor KWH savings x KWH Rate

F.3. Water Conservation Calculations Annual Water Savings (Gallons):

Toilets and Urinals = (Pre Gallons per Flush – Post Gallons per Flush) x Frequency per Occupant x Number of Occupants x Days per Year

Sinks / Shower Heads = (Pre Flow Rate GPM – Post Flow Rate GPM) x Avg. Time of Use x Frequency per Occupant x Number of Occupants x Days per Year

Dish Sink = (Pre Flow Rate GPM – Post Flow Rate GPM) x Avg. Time of Use per Day x Days per Year

Annual Heating Saving (MMBTU) = Gallons per Year x (Hot Water Temperature – City/Well Water Temperature) x 8.346 lbs/gal / Heater Efficiency / 1,000,000

Annual Dollar Saving ($) = (Gallons Saved) x (Water Rate $/gal + Sewer Rate $/ gal) + MMBTU Savings x (1/MMBTU/Unit of Fuel) x $/ Unit of Fuel

F.4. Plug Load Management Calculations Using logging data, average the wattage draw of each device during the scheduled “off” periods of each facility.

KWH Savings = Pre KWH Measurement – Post KWH Measurement



F.5. Chiller Replacement Calculations Trended data will be taken for a period of 30 days, every year of the Performance guarantee, during the summer and winter seasons.

Chiller Load (Tonnage) = (Supply Temp – Return Temp) x Chiller Loop GPM x 8.346 lbs/gallon x 60 / 12,000

Chiller kW = Trended current x measured voltage x 0.9 assumed power factor / 1000

Outdoor Air Temperature = trended using data logger or building automation system

Using calculated kW/ton and measured outdoor air temperature, a comparison of pre and post chiller load efficiency at these values will be made. For example, if the post measurement data results in 95F outdoor air temperature and, based on tonnage, the chiller is 80% loaded, the calculated post kW/ton will be compared to the pre modeled kW/ton efficiency under those same conditions.

Bin weather data will be used to obtain operating hours during the year. For example, if the measured outdoor air temperature is 95F, Bin weather data will be used to obtain the total hours in a year that the outdoor air temperature is 95F.

The bin weather hours will be used to determine kWh savings.

Annual Chiller Savings (kWh) = (kW/Ton Pre – kW/Ton Post) x Bin Weather hours based on measured outdoor air temperature.

Annual Chiller Savings (kW) = (kW/Ton Pre – kW/Ton Post) x calculated cooling capacity (tons) x 12 months

Annual Dollar Savings ($) = KWH Savings x KWH Rate + KW Savings + KW Rate

F.6. Cultural Center RTU Replacement Calculations The following saving calculations will be executed for one of each unit type of RTU replaced. The trending session will be conducted for 14 days every year to determine the annual energy savings.

Unit Energy Savings:

Annual Savings (KWH) = Baseline hours x (Pre Unit KW – Post Unit KW)

Annual Saving KW = (Pre Unit KW – Post Unit KW) x 12 months

Annual Dollar Savings ($) = KWH Savings x KWH Rate + KW Savings + KW Rate

F.7. DPW Administration Calculations Savings generated by scheduling the HVAC equipment serving the Administration building shall be based on the new equipment’s operating hours. Both units will be trended in order to verify and validate the guaranteed reduction in hours of operation.

Unit Energy Savings:



Annual Savings (KWH) = (Trended Baseline Operating Hours x Pre Unit KW) – (Trended Operating Hours x Post Unit KW)

Annual Dollar Savings ($) = KWH Savings x KWH Rate

F.8. Others Option E (Stipulation) has been selected to verify Savings for the following FIMs. No additional measurement s and savings calculations will be taken.

F.9. Methodology to Adjust Baseline Baseline development is critical to the success of an Energy Performance Contract. Therefore, Siemens Industry performs the upfront analysis and measurements required to adequately and appropriately define the existing operation of the affected systems.

Siemens first establishes baseline energy use for a facility by analyzing historical utility bills, developing system level energy models, performing an energy balance of the major energy systems and reconciling the energy balance with actual utility bill usage data. Typically, Siemens prefers using system level energy baseline models in addition to building level utility bill models, which are heavily influenced by variations in building usage, occupancy, weather, equipment changes and installed plug loads (computers, etc.). Operating characteristics are more easily measured and variations can be isolated with system level models. The baseline models are developed using in-house and third party software programs such as Trane Trace and DOE-2. Industry accepted energy calculation methodologies, such as those developed by ASHRAE, are used in all models.

Siemens typically uses the MetrixTM software application by SRC Technologies for these whole building baseline models. MetrixTM utilizes linear regression analysis methods and allows for modeling of baseline adjustments due to material facility changes. The “Metrix” software uses the following calculations in its regression analysis:



BL = B x (Ti - Ti-1) + CH x HDDBH,I + Cc x CDDBC,I + C1 x U1,I + C2 x U2,I + C3 x U3,i

where:

BL = Baseline (Utility Units)

B = Baseload consumption per unit time (Utility Units/day)

Ti - Ti-1 = time interval between date Ti and Ti-1 (days)

CH, CC = Coefficients for Heating and Cooling Degree-days (Utility units/ deg-day)

HDDBH,I = Time history of Heating degree-days °F-day or °C-day)

CDDBC,I = Time history of Cooling degree-days (°F-day or °C-day)

BH, BC = Heating and Cooling degree-day base temperatures (°F-day or °C-day)

C1, C2, C3 = Coefficients for user variables 1,2,3 (e.g. occupancy/schedule, space utilization, added load)

U1,I, U2,I, U3,I = Coefficients for user variables 1,2,3

The baseline for each month of the annual savings period for each energy type for kW demand adjustments will be calculated as follows:

DBl = B + CH x HDDBH,I + Cc x CDDBC,I + C1 x U1,I + C2 x U2,I + C3 x U3,i

where:

B = Baseload consumption per unit time (Utility Units/day)

Ti - Ti-1 = time interval between date Ti and Ti-1 (days)

CH, CC = Coefficients for Heating and Cooling Degree-days (Utility units/ deg-day)

HDDBH,I = Time history of Heating degree-days (°F-day or °C-day)

CDDBC,I = Time history of Cooling degree-days (°F-day or °C-day)

BH, BC = Heating and Cooling degree-day base temperatures (°F-day or °C-day)

C1, C2, C3 = Coefficients for user variables 1,2,3 (occupancy/schedule, space utilization, added load)

U1,I, U2,I, U3,I = Coefficients for user variables 1,2,3



Monthly energy savings will be calculated as follows:

ES = BL - AU and DS = DBl - Dp

where:

ES = monthly unit energy savings

BL = Baseline

AU = post retrofit monthly energy usage

DBl = adjusted demand

DS = kW demand savings

Dp = post retrofit kW demand usage

The energy costs avoided will be calculated as follows:

CS = ((DS x dr) - Adc) + (( ES x uc) - Aec) + Os

where:

CS = Monetary savings

ur = The greater of the floor price of demand and the current costs

uc = The greater of the floor price of energy and the current costs.

For energy sources concerning utility rate structures, the cost decreases with increasing usage. This cost refers to the marginal unit cost from a month's utility bill. For electricity, this marginal cost shall be determined for energy (starting with the amount paid for the last kilowatt-hour purchased including fuel adjustment cost) and demand (amount paid for the last kilowatt purchased) including, if applicable, the effect of demand on the energy cost.

In order to gather data for the baseline calculations, our engineers will perform a site audit. The specific tasks conducted during the preliminary building audits which directly involve baseline model development include the following:

• In-depth site investigations on a room-by-room, system-by-system basis

• Observation of building and equipment conditions

• Observation of system performance during both occupied and unoccupied periods.

• Review of available drawings

• Analysis of historical electric, natural gas and water bills



• Review of control system design and operation

• Interviews with building operators and users.

• Collection of field data including equipment specifications, control set points, etc.

• Field measurements, as necessary, to determine or confirm system operation

• Calculation of individual system baseline energy usage with computerized ASHRAE bin data models

• Consolidation of system level energy models into overall building energy balance

• Analysis of actual utility bill usage data and applicable rate structures

• Reconciliation of system models and energy balance with actual utility bill usage data

The baseline utility usage and energy balances are used to substantiate the parameters defined in the baseline system models, such as power draws, fuel rates, efficiencies, space conditions, control sequences, set-points, loads, operating hours, etc. Savings projections are developed by evaluating “before” and “after” system models based on the recommended changes to system operation.

Siemens may perform a series of ‘pre-measurements’ using either temporary metering or spot measurement as described below.

F.10. Temporary Metering Temporary metering involves the installation of metering equipment such as:

• Light loggers to verify operating hours, lumens in a given space and, in many cases, occupancy

• Data loggers (measuring amperage), BAS trends, BAS schedules and/or time clock settings to verify or operating hours and peak electric demand contributions of equipment.

These extended measurements provide the basis for predicting the energy usage and loads associated with various pieces of equipment. This approach also provides an indication of the influence of factors such as weather and operating schedules that impact the operation of the equipment. For example, the following calculations indicate the energy usage of the chilled-water systems from the measurements performed:

Both the loads and energy of the chiller system can be graphed as a function of outside air temperature for occupied and unoccupied periods. Then a linear correlation of the loads’ outside air temperature and energy usage and outside air temperature produces a method to predict the loads and energy in the future.

F.11. Spot Metering Spot metering is used when there is little variation in equipment operation over known or conservative operating hours. For example, in conjunction with the temporary metering using light loggers or BAS trends/schedules, the energy draw of a constant speed motor does not vary significantly while it is on. A one-time measurement of the motor power draw provides indication of the motor draw for all operating hours. This is also performed on lighting circuits (usually a minimum of 10%). The Voltage, Amperage, and Kilowatts for each are measured and noted. These measurements are typically witnessed and approved by the customer.

The measurement of operating hours is then multiplied by the spot measurements to define the baseline energy usage.

[ ] [ ] [ ]hrursNumberOfHokWPowerkWhEnergy ×=

F.12. Adjustments to Baseline and Guaranteed Levels of Savings

During the guarantee period, there may be changes in a facility's usage and/or operation for which a calculated adjustment to the baseline is necessary.

The energy baseline or actual energy performance can be adjusted for any of the following:

• Local weather conditions

• Occupancy level changes, hours of operation



• Structural modifications, modifications to energy consuming equipment

• Damaged or malfunctioning equipment

• Any variances from the proposed operating schedules, strategies and conditions upon which the calculated savings are based on, and described in the "Contracted Baseline" that could affect energy usage

Prior to installation of new equipment, adjustments to the baseline demand may be required for non-operating components that are normally operating or intended for operation. In addition, after each installation, adjustments to baseline demand may be required because of factors such as remodeling or changes in occupancy. The Customer can recommend a suitable method for making adjustments to the baseline, if necessary. Alternately, Siemens will base the adjustments on engineering calculations that adequately describe the increased/decreased requirements.

The annual reports will document changes in conditions that may affect savings persistence. When using regression analysis, the greater of the baseline loads (and therefore, the energy usage) or the post-installation loads plus the calculated interactive effects of related measures will account for changes in facility operation or occupancy. The higher of the current or baseline utility costs will be used to determine the dollar savings associated with the measure on an annual basis.



G. Schedule G – Construction and Installation Schedule

Proprietary and Confidential © Siemens Industry IGA – Volume- 1 | 123


H. Schedule H - Systems Start-Up and Commissioning; Operating Parameters of Installed Equipment

H.1. System Start-up and Commissioning

As the Performance Contractor for the City of Hallandale project, Siemens Industry, Inc. (Siemens) is committed to making sure all Facilities Improvement Measures (FIM) proposed to the City of Hallandale will function as designed and reduce energy costs. In order to insure that each FIM is properly installed and functioning as designed, Siemens will commission and verify the quality and functionality of each FIM.

DEFINITION AND OBJECTIVE OF THE COMMISSIONING PROCESS:

The main objective of commissioning is to affect the safe and orderly handover of systems from the Contractor to the Owner, guaranteeing its operability in terms of performance, reliability, safety and traceability. Additionally, when executed in a planned and effective way, commissioning normally represents an essential factor for the fulfillment of schedule, costs, safety and quality of the project.

Many of the project facility improvement measures (FIMs) are relatively simple in nature and do not require extensive commissioning work, while other project FIMs require a more extensive commission process. The procedures/steps for both scenarios are covered on the following pages.

It is important to note that often in a performance contract only a portion of a system is replaced or upgraded. For example, if a facility has an existing energy management system (EMS) and the Performance Contractor intends to expand the EMS as part of a project, only the expanded portion of the EMS is relevant in the commissioning procedures for an EMS.

Accordingly, the FIMs that are being proposed to the City of Hallandale by Siemens Industry, Inc. are as follows:

• Interior lighting

• Water conservation

• Mechanical Insulation

• Chiller replacement

• RTU replacement
